Product Details

  • The ATC diversified SLA series Is designed to protect three phase equipment against phase loss, under voltage and phase reversal conditions
  • With normal operating voltages applied in the proper ABC sequence the internal relay will energize (PICK UP)
  • When incorrect phase sequence or phase loss occurs or the three phase voltages fall below the drop out voltages the relay will de-energize (DROP OUT)
  • Both Delta and Wye systems may be monitored
  • In Wye systems, connections to neutral are NOT required
  • NOTE: when a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage.
  • However with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted.
